(A) Green fluorescent protein (GFP) constructs evaluated for the promoter activity of p28-Omp genes 14 and 19. The pPROBE-NT plasmids containing the promoterless GFP gene (2 and 3) and upstream sequences of genes 14 and 19 in front of the GFP gene (1 and 4, respectively) and a construct containing no promoter sequence were evaluated for GFP expression in E. coli. (B) LacZ constructs evaluated for the promoter activity of p28-Omp genes 14 and 19. The pBlue-TOPO vector containing promoterless lacZ gene (pBlue-TOPO) and upstream sequences of genes 14 and 19 inserted in forward (14-F and 19-F) and reverse orientations (14-R and 19-R) were evaluated for β-galactosidase activity in E. coli. Data are presented with SD values calculated from four independent experiments (P ≤ 0.001).
